Abstract

Introduction Transthyretin (ATTR) amyloidosis is responsible for the majority of cardiac amyloidosis (CA) cases and can be reliably diagnosed with bone scintigraphy and the visual Perugini score. We aimed to implement a quantification method of cardiac amyloid deposits in patients with suspected cardiac amyloidosis and to compare performance to visual scoring. Methods and materials 136 patients received 99mTc-DPD-bone scintigraphy including SPECT/CT of the thorax in case of suspicion of cardiac amyloidosis. Imaging phantom studies were performed to determine the scaling factor for standardized uptake value (SUV) quantification from SPECT/CT. Myocardial tracer uptake was quantified in a whole heart volume of interest. Results Forty-five patients were diagnosed with CA. A strong relationship between cardiac SUVmax and Perugini score was found (Spearman r 0.75, p p p Conclusion We demonstrate an accessible and accurate quantitative SPECT approach in CA. Quantitative assessment of the cardiac tracer uptake may improve diagnostic accuracy and risk classification. This method may enable monitoring and assessment of therapy response in patients with ATTR amyloidosis.

Abstract

ZusammenfassungRasch zunehmende Evidenz und gehäufte Berichte zeigen, dass COVID-19 keine isolierte Erkrankung der Lunge ist, sondern eine Multisystemerkrankung mit wesentlicher Beteiligung des Herz-Kreislauf-Systems. Mittlerweile konnte gezeigt werden, dass bis zu 30% der COVID-19-Krankheitsverläufe mit einer Troponinerhöhung im Sinne einer Myocardial Injury assoziiert sind. Je schwerer der Krankheitsverlauf ist, desto häufiger scheint eine Herzbeteiligung zu sein. Darüber hinaus gibt es Hinweise, dass eine SARS-CoV-2-Infektion nicht nur zu akuten kardialen Komplikationen, sondern auch langfristig zu Schädigungen des Herzmuskels führen kann. Der komplexe Pathomechanismus der viralen Myokardschädigung ist in Gänze noch nicht verstanden und Gegenstand aktueller Forschung. Die Herzmuskelschädigung durch eine SARS-CoV-2-Infektion kann durch direkte Interaktion des Virus mit spezifischen Rezeptoren der Kardiomyozyten erfolgen oder indirekt als Folge der systemischen Entzündung mit begleitender Endothelitis.

Abstract

We aimed to determine, whether epicardial adipose tissue (EAT) as local source of inflammation, as well as its change over time, associates with the development of heart failure with preserved ejection fraction (HFpEF) in patients with coronary artery disease.We retrospectively included 379patients (aged 65.2 ± 11.7 years, 70.2%male) with coronary artery disease but without heart failure at baseline, undergoing clinical and echocardiographic assessment in 2010-2013 and receiving a second assessment in 2014-2018. EAT thickness was defined as space between the myocardium and the pericardium and indexed (EATi) by body surface area. Change in EATi was calculated as the difference of follow-up and baseline EATi. HFpEF was defined according to presence of dyspnea, elevated natriuretic peptides, and structural and/or functional alterations on echocardiography in accordance with current European Society of Cardiology guidelines. During a median follow-up of 4.3 years, 142patients (37.5%) developed HFpEF. Patients with onset of HFpEF had higher EATi at baseline (2.4 ± 1.3 vs. 1.9 ± 0.9 mm/mEATi is associated with the development of HFpEF. The finding of changes in EATi altering the risk of HFpEF manifestation support the rationale for further research on epicardial fat modulation as a treatment target for HFpEF.

Abstract

BACKGROUND There were gaps between guidelines and practice when surgery was the only treatment for aortic stenosis (AS). OBJECTIVES This study analyzed the decision to intervene in patients with severe AS in the EORP VHD (EURObservational Research Programme Valvular Heart Disease) II survey. METHODS Among 2,152 patients with severe AS, 1,271 patients with high-gradient AS who were symptomatic fulfilled a Class I recommendation for intervention according to the 2012 European Society of Cardiology guidelines; the primary end point was the decision for intervention. RESULTS A decision not to intervene was taken in 262 patients (20.6%). In multivariate analysis, the decision not to intervene was associated with older age (odds ratio [OR]: 1.34 per 10-year increase; 95% CI: 1.11 to 1.61; P = 0.002), New York Heart Association functional classes I and II versus III (OR: 1.63; 95% CI: 1.16 to 2.30; P = 0.005), higher age adjusted Charlson comorbidity index (OR: 1.09 per 1-point increase; 95% CI: 1.01 to 1.17; P = 0.03), and a lower transaortic mean gradient (OR: 0.81 per 10-mm Hg decrease; 95% CI: 0.71 to 0.92; P < 0.001). During the study period, 346 patients (40.2%, median age 84 years, median EuroSCORE II [European System for Cardiac Operative Risk Evaluation II] 3.1%) underwent transcatheter intervention and 515 (59.8%, median age 69 years, median EuroSCORE II 1.5%) underwent surgery. A decision not to intervene versus intervention was associated with lower 6-month survival (87.4%; 95% CI: 82.0 to 91.3 vs 94.6%; 95% CI: 92.8 to 95.9; P < 0.001). CONCLUSIONS A decision not to intervene was taken in 1 in 5 patients with severe symptomatic AS despite a Class I recommendation for intervention and the decision was particularly associated with older age and combined comorbidities. Transcatheter intervention was extensively used in octogenarians. (J Am Coll Cardiol 2021;78:2131-2143) (c) 2021 by the American College of Cardiology Foundation.

Abstract

Transthyretin (ATTR) amyloidosis is responsible for the majority of cardiac amyloidosis (CA) cases and can be reliably diagnosed with bone scintigraphy and the visual Perugini score. We aimed to implement a quantification method of cardiac amyloid deposits in patients with suspected cardiac amyloidosis and to compare performance to visual scoring.136 patients receivedForty-five patients were diagnosed with CA. A strong relationship between cardiac SUVmax and Perugini score was found (Spearman r 0.75, p 0.0001). Additionally, tracer uptake in bone decreased with increasing cardiac SUVmax and Perugini score (p 0.0001). ROC analysis revealed good performance of the SUVmax for the detection of ATTR-CA with AUC of 0.96 ± 0.02 (p 0.0001) with sensitivity 98.7% and specificity 87.2%.We demonstrate an accessible and accurate quantitative SPECT approach in CA. Quantitative assessment of the cardiac tracer uptake may improve diagnostic accuracy and risk classification. This method may enable monitoring and assessment of therapy response in patients with ATTR amyloidosis.

Abstract

Background: Mitral valve orifice area (MVOA) is a key parameter in edge-to-edge mitral valve repair. 3-dimensional transesophageal echocardiography (TOE) assessment of MVOA is the gold standard. In clinical routine, mitral valve stenosis is frequently estimated by mean pressure gradient (MPG) and pressure half time (PHT), which are influenced by the degree of regurgitation and heart rate (HR). Objectives: We aimed to determine the association of MPG, PHT, regurgitant area, and HR with MVOA with mitral valve regurgitation in patients undergoing interventional mitral valve repair. Methods: TOE images from patients undergoing edge-to-edge mitral valve repair were evaluated. MVOA was measured from 3-dimensional volume datasets using multiplanar reformations. Linear regression analysis was used to determine the association of MPG and PHT with MVOA. Results: By implantation of 1.24 devices in 51 patients (aged 80±13years, 49%male), MVOA was reduced from 5.77±2.17cm² to 2.96±1.03cm². MVOA was modestly inversely correlated with MPG (r=-0.45, p

Abstract

Das akute Lungenversagen (ARDS) ist trotz umfangreicher, jahrzehntelanger Bemuhungen weiterhin mit einer hohen Mortalitat verbunden und stellt hochste Anspruche an die intensivmedizinische Therapie. In den letzten Jahren konnten Fortschritte in der ARDS-Therapie verzeichnet und erstmals ein messbarer Ruckgang der Mortalitat erzielt werden. Grundlage einer effektiven Therapie ist die zeitnahe Erkennung eines drohenden Lungenversagens, eine fruhe und sachgerechte Behandlung der Grunderkrankung sowie eine adaquate Beatmungstherapie zur Vermeidung weiterer beatmungsassoziierter Lungenschaden. Die neue ARDS-Definition sowie die Kernelemente der Therapie werden hier zusammengefasst.

Abstract

Aims Diastolic dysfunction is highly prevalent, and ageing is the main contributor due to impairments in active cardiac relaxation, ventriculo-vascular stiffening, and endothelial dysfunction. Nitric oxide (NO) affects cardiovascular functions, and NO bioavailability is critically reduced with ageing. Whether replenishment of NO deficiency with dietary inorganic nitrate would offer a novel approach to reverse age-related cardiovascular alterations was not known. Methods and results A dietary nitrate supplementation was applied to young (6 month) and old (20 month) wild-type mice for 8 weeks and compared with controls. High-resolution ultrasound, pressure–volume catheter techniques, and isolated heart measurements were applied to assess cardiac diastolic and vascular functions. Cardiac manganese-enhanced magnetic resonance imaging was performed to study the effects of dietary nitrate on myocyte calcium handling. In aged mice with preserved systolic function, dietary nitrate supplementation improved LV diastolic function, arterial compliance, and coronary flow reserve. Mechanistically, improved cardiovascular functions were associated with an accelerated cardiomyocyte calcium handling and augmented NO/cyclic guanosine monophosphate/protein kinase G signalling, while enhanced nitrate reduction was related to age-related differences in the oral microbiome. Conclusion Dietary inorganic nitrate reverses age-related LV diastolic dysfunction and improves vascular functions. Our results highlight the potential of a dietary approach in the therapy of age-related cardiovascular alterations.

Abstract

Background Macrophage migration inhibitory factor (MIF) is cardioprotective in myocardial ischemia/reperfusion (I/R) injury. MIF reduces apoptosis by its extracellular chemokine-like functions and the inhibition of the JNK pathway via intracellular JAB 1 binding. Unbound intracellular MIF reduces oxidative stress via its oxidoreductase activity. S -Nitros(yl)ation of MIF after nitrite application in I/R injury is a phenomenon of the early phase of reperfusion. S -Nitros(yl)ation enhances MIF’s cardioprotective properties: increase of the enzyme-like activity, reduction of infarct sizes and apoptosis. S -Nitros(yl)ation of MIF and MIF/JAB 1 interaction both depend on MIF’s cysteine 81. Whether S -nitros(yl)ation of MIF influences MIF/JAB 1 interaction during different phases of reperfusion and whether this affects MIF’s intra-and extracellular properties, is unclear. Hypothesis S -Nitros(yl)ation of MIF regulates its binding to JAB 1, its localization and its consecutive signaling pathways differentially in the various phases of reperfusion. Methods/Results TUNEL staining of murine hearts after in vivo I/R injury showed reduced apoptosis after S -nitros(yl)ation of MIF (14.5 ± 1.0% vs. 8.0 ± 3.5%, p In early phase of reperfusion, MIF/JAB 1 interaction was reduced upon S -nitros(yl)ation (0.3 ± 0.06% vs. 0.11 ± 0.04%, n = 4, p n = 5). Intracellular MIF protects from ROS induced damage: aconitase acitivity was higher after S -nitros(yl)ation than in control (2.1 ± 0.5 mU/mg protein vs. 1.25 ± 0.5 mU/mg protein, n = 3, p After 4 h of reperfusion, S -nitros(yl)ation and its effect on MIF/JAB 1 interaction was vanished: MIF/JAB 1 interaction was not different in both groups (0.34 ± 0.09% vs. 0.32 ± 0,05%, n = 5, p = ns). MIF concentrations in coronary effluent were higher after S -nitros(yl)ation than in control (4.9 ± 2 ng/min/g heart vs. 0.7 ± 0.3 ng/min/g heart, n = 5) showing time-delayed MIF release. Conclusion S -Nitros(yl)ation of MIF in I/R-injury reduces the MIF/JAB 1 interaction and MIF’s secretion. This detains MIF in the cell during early phase of reperfusion, where MIF reduces oxidative stress. In late phase-when S -nitros(yl)ation of MIF has vanished-MIF is released to the extracellular space, where other signaling pathways can be activated. Disclosure Nothing to disclose.
